Each securing projection 49 has an upper corner 60. When the securing projections 49 are received in the securing recesses 58, the upper corner 60 of each securing projection 49 engages the respective connecting member 44 within the securing recess 58, thereby inhibiting movement of the support arrangement 36 from the support position.

FIG. 11 shows the underside of the container 10. The base 16 defines a depression 62 extending over a large proportion of the base 16. A plurality of strengthening members 64 are provided in the depression 62 to strengthen the base 16. Each strengthening member 64 is substantially straight, and extends diagonally across the depression 62.

The base 16 also defines positioning concavities 66 at each opposite edge 18B, adjacent the second wall members 24. The concavities 66 are arranged to correspond in size and shape to the locating projections 40. As a result, when the container 10 is stacked on the support arrangements 36 of a lower further container 10, the locating projections 40 of the upper container 10 are received in the concavities 66 of the support arrangements 36 of the lower container 10, thereby locating the upper container 10 on the lower container 10.

FIG. 12 is a close up of a region of one of the second wall members 24 in which the second wall member 24 has an opening 68, and an inner skin 70 is provided over the opening 68. The inner skin 70 is attached to the inner surface of the second wall member 24, and defines a pocket 72 in which a label can be disposed. The inner skin 70 includes an upper semi-circular recess 74 into which a finger can be inserted to remove the label. The opening is visible through the semi-circular recess 74 in FIG. 12 , and can be seen in FIG. 5 . The label can be viewed through the opening 68.

FIG. 13 shows the use of dividers 76 in the internal region 14 of the container 10. The dividers 68 can be secured to the first wall members 22 by means of fastening formations 78, which can be received in fastening slots 80 in the first wall members 22.

In use, both support arrangements 36 are moved to their respective stowed positions to allow the container 10 to be loaded. The container 10 can be carried by the handles to a destination, such as a storage point to a means of transport. When so carried, the support arrangements 36, being disposed in the main receiving area 34 just above the through hole 26, bear some of the load being carried.

When the container 10 has been carried to the destination, the user can press inwardly on the locating projections 40 on the central portions 38. This moves the support arrangements 36 inwardly of the internal region 14, to pivot the support arrangements 36 from the stowed positions to the support positions.

When the support arrangements 36 are so pivoted, the guide members 54 move in the guide slots 56, thereby guiding the support arrangements 36 to their support positions.

When the support arrangements 36 reach their support positions, the securing projections 49 on the subsidiary shoulders are received in the securing recesses 58. The aforesaid upper corners 60 of the securing projections 49 engage the connecting members 44 within the respective securing recesses 58.

In the support position of each of the support arrangements 36, the locating projections 40 extend upwardly. A further similar container 10 can be disposed on the container 10, the further container 10 being stacked upon the support arrangements 36 in their support position.

When so stacked, the locating projections 40 are received in the concavities defined in the base 16 of the further container 10. This locates the further container 10 on the container 10.

If desired, instead of pressing inwardly on the locating projections 40 to move the support arrangements 36 from their stowed positions, the user may insert a hex key into each of the hexagonal sockets 52. Turning the hex key pivots the respective support arrangement 36 between the stowed and support positions.

The above described embodiment provides the advantage that, the provision of the locating indentation 28 allows the container 10 to be loaded and unloaded by automation.

When the support arrangement 36 is in the stowed position, the support arrangement 36 is flush with the lower region of the second wall member 24. As a result, the support arrangement 36 provides a free passage for items in the container 10 to be emptied therefrom when the container 10 is turned upside down.

The subsidiary shoulder formations 46 allow the weight of containers 10 stacked on the support arrangement 36 to be transmitted to the first wall members 22.

Various modifications can be made without departing from the scope of the invention. For example, the second wall members 24 are devoid of the through hole 28.

A further modification is shown in FIGS. 14 to 17 , in which a further container 10A is shown. The further container 10A is a modified version of the container 10.

The further container 10A has all the features of the container 10, shown in FIGS. 1 to 13 , with the exception of the differences discussed below. In FIGS. 14 to 17 , the features of the further container 10A are designated with the same reference numerals as the corresponding features shown in the previous Figures.

In FIGS. 14 to 16 , the guide tracks are in the form of curved guide shoulders 56A provided in the subsidiary wall portions 48.

Also, in the modification shown in FIGS. 14 to 17 , each support arrangement 36 comprises three of the locating projections, namely a central locating projection 40A and two outer locating projections 40B (see FIG. 16 ). The central locating projection 40A is received in the locating indentation 28, and the two outer locating projections 40 are received in further locating indentations 28A defined in the inner skins 70.

The further container 10A possesses the projection 54. In the container 10A, the projection 54 engages the shoulder 56A, and slides therealong when the support arrangement 36 moved between the support position and the non-support position.

Referring to FIG. 17 , the base 16 of the container 10A also defines three positioning concavities 66 at each opposite edge 18B, adjacent the second wall members 24. The three positioning concavities 66 comprise a central positioning cavity 66A and two outer positioning concavities 66B.

The central concavities 66A are arranged to correspond in size and shape to the central locating projections 40A. The outer concavities 66B are arranged to correspond in size and shape to the outer locating projections 40B.

As a result, when the container 10A is stacked on the support arrangements 36 of a similar further container 10A, in which the support arrangements 36 are in their support positions. The central and outer locating projections 40A, 40B of the upper container 10A are received in the respective central and outer positioning concavities 66A, 66B of the support arrangements 36 of the lower container 10A, thereby locating the upper container 10A on the lower container 10A.
